Electricity is

effectively reduced. What to do
to make electric heating relatively cheap?
One of the ways to
reduce the cost of electric heating is the use of dual-zone tariffs offered by
energy utilities. Accounting for
them, you can pay almost half less for energy consumed at night, for a short
time during the day and on Saturdays and on Sundays. As a result, the costs of electric
heating can also be nearly half as much as in the case of using a 24-hour
tariff.Provided that you use the ones that can accumulate the heat generated
during the cheaper rate and put them into the rooms for a few hours after
disconnecting the power, when the fees are higher.
Heating devices for
electric heating
For this application,
electric storage heaters (stoves) are equipped with inserts made of materials
with a large heat capacity.Their heating power should be selected so that the
cartridge can warm up when the electricity is cheaper - it should be at least
twice as high as the heat demand in the room that heats up. The amount of accumulated heat should
be sufficient to heat the rooms at the time of the higher electricity payment
(during peak hours).
Accumulation heaters are
static - returning heat with constant power or dynamic (with dynamic
discharge). The intensity of
electric heating is regulated in them by changing the rotational speed of the
fan that forces the air flow around the accumulation cartridge. If it is controlled by an advanced
regulator with temperature sensors and so-called residual heat, equipped with a
clock, it is possible to optimize the electricity consumption (and thus reduce
heating costs) so that the room temperature reaches the desired value during
the lower energy payment and maintained at the required level, when the heater
does not charge it (during peak hours).
Accumulation in the
floor
Electric storage heating
can also be made from heating cables placed under the floor. Since ordinary floor heating varies in
the thickness of the undercoat layer heated by the wires. To accumulate the necessary heat
supply, it should be between 7 and 15
cm . Therefore, the heating power of the
ducts must also be increased - at least by 30% in relation to the installation
not adapted to work with longer intervals (without special heat storage
capacity). It is necessary that
they can warm up the concrete storage mass in a sufficiently short time.
